Environmentally friendly paving continues to be on the forefront of our agenda for the future.

This paver has gained world-wide acceptance as the paver-of-choice for performance, and as an environmental solution for drainage. Only the patented “L” shaped design allows you to achieve a superior lock-up that can withstand even the heaviest of loads residentially and commercially. The innovative design creates small voids between the pavers providing drainage into the sub-base.

Mechanical Installation

Eco-Optiloc™ has the highest mechanical installation rates of any interlocking permeable paver. The patented L-shaped design makes the paver clusters easy to install quickly and accurately. Installation rates up to 12,000 sq.ft. per machine per day have been documented. This makes Eco-Optiloc™ a very competitive permeable pavement that can be installed even in adverse weather conditions.

Surface Texture
EnduraColor Facemix Technology
EnduraColor products are manufactured in a two-step process which combines a base of coarser aggregates for a stronger foundation, with concentrated color and wear-resistant finer aggregates on top. EnduraColor products are highly resistant to fading because the top layer prevents large, lighter color aggregates from showing through.
